BACKGROUND ART

An extracellular matrix consists of collagen, proteoglycan, etc., has a function to support tissues, and plays a role in a maintaining of a cell functions, for example propagation, differentiation, adhesion, or the like. Matrix metalloproteinases (MMP) such as gelatinase, stromelysin, collagenase, and the like have an important role in degradation of an extracellular matrix, and these enzymes work for growth, tissue remodeling, etc. under physiological conditions. Therefore, it is considered that these enzymes participate in progression of various kind of diseases involving breakdown and fibrosis of tissues, such as osteoarthritis, rheumatoid arthritis, corneal ulceration, periodontitis, metastasis and invasion of tumor, and virus infection (for example, HIV infection). At the present time, it is not clear which enzyme participates in the above diseases seriously, but it is considered that these enzymes at least participate in tissue breakdown. As metalloproteinase inhibitors of amino acid derivatives, for example hydroxamic acid derivatives of amino acids (JP-A-6-2562939), carboxylic acid derivatives of amino acid and/or their hydroxamic acid derivatives (WO95/35276), etc. are disclosed.

BEST MODE FOR CARRYING OUT THE INVENTION

Compounds (Ia) and (Ib) of the invention are able to be synthesized from the corresponding α-amino acids represented by the formula (XV) by means of the following 6 synthetic methods. Generally, it is possible to produce the compounds of the invention by means of the method A. Each classified type of the compounds is possible to be produced by means of methods the B to F. However, these methods are only examples to produce the compounds represented by the formula I. A compound represented by the formula I produced by any other method is included in this invention.

Method A: A general synthetic method of the compound represented by the formula I.

Method B: A synthetic method of the compound wherein and R³ is optionally substituted arylene or optionally substituted heteroarylene, R⁴ is --C.tbd.C--, and R⁵ is optionally substituted aryl or optionally substituted heteroaryl.

Method C: A synthetic method of the compound wherein R³ is optionally substituted arylene or optionally substituted heteroarylene, R⁴ is a bond, and R⁵ is optionally substituted aryl or optionally substituted heteroaryl.

Method D: A synthetic method of the compound wherein R³ is optionally substituted arylene or optionally substituted heteroarylene, R⁴ is --CO--NH--, and R⁵ is optionally substituted aryl or optionally substituted heteroaryl.

Method E: A synthetic method of the compound wherein R³ is optionally substituted arylene or optionally substituted heteroarylene, R⁴ is tetrazol-diyl, and R⁵ is optionally substituted aryl or optionally substituted heteroaryl.

Method F: A synthetic method of the compound wherein R³ is optionally substituted arylene or optionally substituted heteroarylene, R⁴ is --CH═CH--, and R⁵ is optionally substituted aryl or optionally substituted heteroaryl.

Details of these methods are explained as follows.

(Method A) ##STR21## wherein R¹, R², R³, R⁴, and R⁵ are as defined above, R¹⁵ is hydrogen atom or a carboxy protective group, R¹⁶ is a hydroxy protective group, and Hal is halogen.

Conversion of compound (XV) to compound (Ia-1) is sulfonation of an amino group of the compound (XV) (process 1). If necessary, after this reaction, N-alkylation, deprotection of a carboxyl protective group, etc. are carried out. Conversion of compound (Ia-1) to compound (Ib-1) is to obtain hydroxamic acid derivatives from carboxylic acid derivatives (process 2). To obtain compound (Ib-1) from compound (Ia-1), compound (Ia-1) may also be reacted with hydroxylamine having a hydroxyl protective group or its acidic salts to give compound (XVI) (process 3), followed by and deprotection (process 4). Conversion to sulfonyl derivatives and hydroxamic acid derivatives are able to be carried out according to an usual method. For example, an amino acid represented by the formula (XV) is reacted with a sulfonating agent such as sulfonyl halide represented by R⁵ --R⁴ --R³ --SO₂ Hal (R³, R⁴, and R⁵ are as defined above; and Hal is halogen) and then hydroxylamine. Each process will hereinafter be described in more detail.

(Process 1)

Some of amino acids represented by the formula (XV) or its acidic salts (e.g., hydrochloride, p-toluenesulfonate, and trifluoroacetate) which are starting materials are commercially available. The other are able to be synthesized in accordance with a method described in Zikkenkagakukoza, vol. 22, IV (nihonkagakukai), J. Med. Chem. 38, 1689-1700, 1995, Gary M. Ksander et. al., etc. some of sulfonating agents are commercially available and the other are synthesized in accordance with a method described Shin-zikkenkagakukoza, vol. 14, 1787, 1978, Synthesis 852-854, 1986, etc. A carboxyl protective group is exemplified by esters (e.g., methyl ester, tert-butyl ester and benzyl ester). Deprotection of this protective group may be carried out by hydrolysis with acid (e.g., hydrochloride and trifluoroacetic acid) or base (e.g., sodium hydroxide) depending on the type of the group, or by catalytic reduction, e.g., under 10% palladium-carbon catalyst condition. To obtain a compound (Ib-1), the esters may directly be converted to hydroxamic acid by the method of process 2. When a compound (XV) is an amino acid wherein R¹⁵ is hydrogen atom, preferable solvents for this sulfonylation are dimethylformamide, tetrahydrofuran, dioxane, dimethylsulfoxide, acetonitrile, water, or mixed solvents thereof. When a compound (XV) is an amino acid wherein R¹⁵ is a protective group such as an ester, a solvent for this sulfonylation is exemplified by the above solvents and mixed solvents of water-insoluble solvents (e.g., benzene and dichloromethane) and the above solvents. A base to be used in this sulfonylation is exemplified by organic bases such as triethylamine, N-methylmorpholine, etc. and inorganic bases such as sodium hydroxide, potassium hydroxide, potassium carbonate, and the like. Usually this reaction can be carried out at ice-cooling to room temperature. When R¹, R³, R⁴, R⁵, or R¹⁵ of compound (Ia-1) contains a functional group(s) possibly interfering this sulfonylation (e.g., hydroxy, mercapto, amino, and guanidino), it can previously be protected in accordance with a method described in "Protective Groups in Organic Synthesis" (Theodora W. Green (John Wiley & Sons)) and then deprotected at an appropriate process. When R² is not hydrogen atom, compound (Ia-1) wherein R² is hydrogen atom is further reacted with haloalkyl (e.g., methyl iodide, and ethyl iodide) or haloaralkyl (e.g., benzyl chloride, and benzyl bromide) in dimethylformamide, tetrahydrofuran, dioxane, and the like at a temperature range of ice-cooling to 80° C., preferably ice-cooling to room temperature, for 3-10 hours, preferably 10-20 hours to give the desired N--R² derivative.

(Process 2)

A hydroxylamine is reacted with compound (Ia- 1) or its reactive derivatives to give hydroxamic acid derivatives (Ib-1). A hydroxylamine is usually used as its acidic salts (e.g., hydrochloride, and phosphate, sulfate: commercially available) in the presence of a base. A base to be used in this reaction is exemplified by organic bases such as triethylamine, N,N-dimethylaniline, N-methylmorpholine, etc. and inorganic bases such as sodium hydroxide, potassium hydroxide, potassium carbonate, etc. When compound (Ia-1) is used as a starting material of conversion to hydroxamic acid, this reaction is carried out in the presence of a peptide condensing agent (e.g., dicyclohexylcarbodiimide, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, N,N'-carbonyldiimidazole, or a mixture of one of the above agents with 1-hydroxybenzotriazole, N-hydroxy sucinicimide, etc.). A solvent for this reaction may be dimethylformamide, tetrahydrofuran, dioxane, dimethylsulfoxide, acetonitrile, water, and mixed solvent thereof. This reaction is carried out at -20° C. to 40° C., preferably ice-cooling to room temperature, for 1 to 16 hours.

Acid anhydrides (especially, mixed acid anhydrides), acid halides, acid azides, and esters can be utilized in this reaction as a reactive derivative of compound (Ia-1). These reactive derivatives are produced by usual methods. For example, the acid anhydride derivatives can be produced by a reaction of compound (Ia-1) with acid halide derivatives (e.g., ethyl chlorocarbonate) in the presence of a base (e.g., triethylamine), and acid halide derivatives can be produced by a reaction of compound (Ia-1) with a halogenation agent (e.g., oxalylchloride, and thionylchloride). Ester derivatives may be inactive or active. Sulfonyl derivatives converted from a compound (XV) wherein R¹⁵ is a carboxyl protective groups (e.g., methyl, tert-butyl, and benzyl) at process 1 can be used as inactive esters without deprotection. Active esters can be produced by a reaction of compound (Ia- 1), carbodiimide reagents (e.g., dicyclohexylcarbodiimide, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide), and hydroxy derivatives corresponding to the active ester residue such as 1-hydroxybenzotriazole, N-hydroxysuccinimide, or the like. A reaction condition of conversion of the reactive derivatives of compound (Ia-1) to hydroxamic acid may be the same as that of conversion of compound (Ia-1) itself to hydroxamic acid. The reactions of processes 1 and 2 are able to continuously be carried out in one-pot reaction.

(Process 3)

A protected hydroxylamine to be used in this reaction includes O-benzylhydroxylamine, O-(p-methoxybenzyl)hydroxylamine, O-(tert-butyl)hydroxylamine, or the like. This reaction condition may be in the same manner as that of process 2.

EXAMPLE 92 Method B ##STR293##

Process 1

To a solution of D-valine methylester hydrochloride (XV-2) (755 mg, 4.5 mmol) in dichloromethane (12 ml) was added N-methylmorpholine (1.49 ml, 3×4.5 mmol) and 5-bromo-2-thiophensulfonyl chloride (1.24 g, 1.05×4.5 mmol) was added under ice-cooling. After being stirred for 15 h. at room temperature, the reaction mixture was washed with 2N HCl, 5% NaHCO₃, and water. The organic layer was concentrated in vacuo, and dried over Na₂ SO₄. The residue was subjected to silica gel column chromatography and the fractions eluting with ethyl acetate/hexane=1/3 were collected and washed with n-hexane to give 1.32 g of the desired compound (XVII-1). Yield 82%. mp. 109-110° C.

Process 2

To a degassed solution of 400 mg (1.12 mmol) of compound (XVII-1) in 5 ml of dimethylformamide was added 222 mg (1.5×1.12 mmol) of 4-methoxyphenylacetylene and 21 mg (0.1×1.12 mmol) of copper iodide (1) under an argon atmosphere. Then 39 mg (0.05×1.12 mmol) of bis(triphenylphosphine)palladium dichloride (II) and 0.47 ml (3×1.12 mmol) of triethylamine were added to the reaction mixture. The resulting mixture was degassed and stirred overnight under an argon atmosphere at 50° C. The reaction mixture was diluted with ethyl acetate. The organic later was washed with 1N HCl, 5% NaHCO₃, and water, dried over Na₂ SO₄, and concentrated in vacuo. The resulting residue was column chromatographed on silica gel. The fractions eluting with n-hexane/ethyl acetate=2/1 were collected and recrystallized from ethyl acetate/n-hexane to give 392 mg of the desired compound (XVIII-1). Yield 86%. mp. 131-132° C.

Process 1

To a solution of 20.94 g (99.8 mmol) of D-valine tert-butyl ester hydrochloride (XV-3) in 200 ml of dichloromethane was added 22 ml (2×99.8 mmol) of N-methylmorpholine and 20.27 g (99.8 mmol) of p-styrenesulfonyl chloride under ice-cooling. After being stirred for 15 h at room temperature, the reaction mixture was washed with 2N HCl, 5% NaHCO₃, water.

Test examples on the compounds of the present invention are described below. The test compounds are the ones described in the Examples and Tables.

Test example

(1) Isolation and purification of MMP-9 (92 kDa, gelatinase B)

Type IV collagenase (MMP-9) was purified according to the methods descrived in the following literature. Scott M. Wilhelm et al., J. Biol. Chem., 264, 17213-17221, (1989), SV40-transformed Human Lung Fibroblasts Secrete a 92-kDa Type IV Collagenase Which Is Identical to That Secreted by Normal Human Macrophages; Yasunori Okada et al., J. Biol. Chem., 267, 21712-21719, (1992), Matrix Metalloproteinase 9 (92-kDa Gelatinase/Type IV Collagenase) from HT 1080 Human Fibrosarcoma Cells; Robin V. Ward et al., Biochem. J., (1991) 278, 179-187, The purification of tissue inhibitor of metalloproteinase-2 from its 72 kDa progelatinase complex.

MMP-9 is secreted from human fibrosarcoma cell line ATCC HT 1080, into its culture medium when it is stimulated with 12-tetradecanoylphorbol-13-acetate (TPA). The production of MMP-9 in this culture was verified by the gelatin zymography as described in the following literature (Hidekazu Tanaka et al., (1993) Biochem. Biophys. Res. Commun., 190, 732-740, Molecular cloning and manifestation of mouse 105-kDa gelatinase cDNA). The condition medium of the stimulated HT 1080 was concentrated and was purified with gelatin-Sepharose 4B, concanavalin A-sepharose, and Sephacryl S-200. The purified pro-MMP-9 (92 kDa, gelatinase B) thus obtained gave a single positive band in the gelatin zymography. Subsequently, activated MMP-9 was obtained by treating the pro-MMP-9 with trypsin.

(2) Assay methods of type IV collagenase inhibitors

Collagenase assay was performed using the activated MMP-9 described above and the substrate supplied in the type IV collagenase activity kit (YAGAI, inc.), according to the manufacturer's protocol. The following 4 assays are performed per compound (inhibitor).

(A) substrate (type IV collagenase), enzyme (MMP-9), inhibitor

(B) substrate (type IV collagenase), inhibitor

(C) substrate (type IV collagenase), enzyme (MMP-9)

(D) substrate (type IV collagenase)

According to the manufacturer's protocol, fluorescent intensity was measured and percent inhibition was determined by the following equation.

    Inhibition (%)={1-(A-B)/(C-D)}×100

IC₅₀ is a concentration at which the percent inhibition reaches 50%. The results are shown in Tables 47 to 54.
